Several studies have been conducted to study developer discussions on different crowd-shared developer platforms, including SO. Seaman et al. studied developer discussion on inspection meetings [1]}. Reiner et al. used content analysis to study developer discussions on software processes [2]}. Gottipati et al. study relevant answers in 3 software forums, Dzone, Tips, and Oracle forums [3]}. Several studies has focused on discussions on microblogs, such as, Twitter [4]}, [5]}, [6]}, and chat communities, such as, HipChat [7]}, IRC messages [8]}, [9]}, and Slack [10]}. Recently, SO Q&A forums have been subject to a number of papers to study various aspects of software development, such as what developers are discussing in general [11]},
or about a particular aspect, e.g., concurrency [12]}, big data [13]}, chatbot development [14]}.
